"It was a big deal. It was fine. He recommended that I get a brand new air conditioning system. The big deal was fine but the additional work was not fine. He said he would take 4 hours but he took more."

"The tenant in my rental property stated she had no cold air blowing. That day I called around for estimates and times to get to it, in busy hot July. I spoke with Moncrief early in the afternoon, and they were able to come out that evening and fix the issue - for a reasonable price, with honesty and integrity. Thanks.

"CAELUM Heating and A/C did an excellent job installing a replacement electric furnace in our attic to connect to an existing heat pump two floors below. He FOUND that the copper cooling line was ORIGINALLY installed at a 3/4” connection but downsized to 1/2” and caused a huge strain on the system. So he handled replacement of the pipe through the full height of the house to ensure the 3/4” connection was attached to 3/4” pipe. He also shared detailed hvac flow engineering with me to explain what the units should be vented like (size and location) based on the unit(s) installed. Paul is very detailed oriented and he loves his job. -S"

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
